Check Digit Verification of cas no

The CAS Registry Mumber 118203-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,2,0 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 118203-17:
(8*1)+(7*1)+(6*8)+(5*2)+(4*0)+(3*3)+(2*1)+(1*7)=91
91 % 10 = 1
So 118203-17-1 is a valid CAS Registry Number.

Four nickel(II)–salophen complexes containing alkyl-imidazolium chains connected at the ortho or meta positions were prepared: N,N′-bis(2-hydroxy-4-methyl-3H-imidazol-1-iumbenzylideneamino)phenylenediamine (1), N,N′-bis(2-hydroxy-3-methyl-3H-imidazol-1-iumbenzylideneamino)phenylenediamine (2), N,N′-bis(2-hydroxy-3-methyl-3H-imidazol-1-iumbenzylideneamino)methyl-3H-imidazol-1-iumphenylenediamine (3), and N,N′-bis(2-hydroxy-4-methyl-3H-imidazol-1-iumbenzylideneamino)methyl-3H-imidazol-1-iumphenylenediamine (4). They protect G-quadruplex DNA (G4-DNA) against thermal denaturation and show KAvalues in the range of 7.4×105to 4×107m?1for G4-DNA models. Complex 4 exhibits an IC50value of 70 nm for telomerase inhibition.
